摘　　要：列车卧具洗涤废水含有的主要污染物为悬浮物和阴离子表面活性剂,采用混凝沉淀-生物活性炭工艺,将洗涤废水处理后回用于冲洗车辆。实践证明,该工艺能够保证出水水质稳定达标。此外,通过使用处理后的再生水冲洗车辆,不仅节约了大量水资源,而且给企业创造了可观的经济效益。Railway laundry wastewater containing suspended solid and anionic surfactant was cleaned by flocculating-sedimentation and biological activated carbon processes respectively. Alter disinfected by ozone and chlorine, the reclaimed water was conveniently used for carriage washing, demonstrated as typical water recycling system of railway industry. The operation practice indicated that the reclaimed water quality can achieve national and local standards. Besides saving water resource, excessive economic benefit has been brought.
